FICON (FIbre CONnection) is IBM's preferred
method of connecting its mainframe computers to storage devices
such as the Enterprise Storage System (Shark). However, native FICON
is limited to distances of 10 kilometres, restricting it to single
site or campus-wide applications.
LightSand has developed a new capability that
allows FICON links to be extended without the use of traditional
FICON directors. The cornerstone of LightSand's FICON extension
capability is the new i-7100F, which extends all of the functionality
of traditional FICON links over distance using conventional IP networks.
This is achieved without the need for expensive director-class SAN
switches. Successful tests conducted at IBM's test labs in Mainz,
Germany, showed the i-7100F to provide transparent compatibility
with existing FICON equipment.
"Enterprise-wide computing and storage
must extend across the entire geographically dispersed enterprise,"
said Philip Black, LightSand's CEO. "Data stored at one site
must be available for analysis anywhere in the organisation. Centralised
backup capabilities can enhance productivity and reduce overall
costs. Effective business continuity plans require that the distance
from the primary site to the backup site exceed any expected disaster
radius. Each of these applications requires the ability to extend
FICON to remote locations, and LightSand's i-7100F makes this possible."
For FICON applications that require the utmost
in performance, the i-7100F can be coupled with LightSand's S-2500B
SONET gateway. The combination of these two devices delivers unprecedented
FICON bandwidth across the WAN while eliminating the need for costly
FICON directors. This pairing provides loss-free, highly efficient
communication and allows the system to move more than 290 MBytes/sec
from one site to another across a single SONET link or DWDM wavelength.
For installations with existing FICON directors, a LightSand S-series
SONET gateway can be deployed to provide FICON extension capabilities.
FICON extended with a LightSand gateway can
be used for a wide variety of applications including remote mirroring
for disaster recovery, storage consolidation for cost containment,
centralised or shared tape operations and even remote printing.
Almost any application that can be run locally over FICON can be
extended to remote locations.
